Ranunculus plant named &#39;ABLEIGONG&#39;

ABSTRACT

A new and distinct  Ranunculus  cultivar named ‘ABLEIGONG’ is disclosed, characterized by brilliant pink colored flowers. Plants produce an above average quantity of flowers of high quality throughout the flowering season. Flower size produced remains large throughout the flowering season. Plants are strong. The new variety is a  Ranunculus , normally produced as a cut flower and potentially useful as an ornamental plant.

Latin name of the genus and species: Ranunculus asiaticus.

Variety denomination: ‘ABLEIGONG’.

BACKGROUND OF THE INVENTION

The new Ranunculus cultivar is a product of a planned breeding program conducted by the inventor, Alberto Biancheri in Camporosso Mare, Italy. The cross resulting in this new variety was made during 2008.

The seed parent is the, unpatented, proprietary variety referred to as Ranunculus ‘A131-02_04/4’. The pollen parent is the unpatented, proprietary variety referred to as Ranunculus ‘B37-01/1’. The new variety was discovered in 2011 by the inventor in a group of seedlings resulting from the 2008 crossing, in a research greenhouse in Camporosso Mare, Italy.

Asexual reproduction of the new cultivar was first performed by vegetative division of buds sprouting from the rhizome of the selected plant. Subsequent propagation has been performed by tissue culture. First propagation took place at a research greenhouse in Camporosso Mare, Italy in 2011 and has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘ABLEIGONG’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ABLEIGONG’ These characteristics in combination distinguish ‘ABLEIGONG’ as a new and distinct Ranunculus cultivar:

-   -   1. Brilliant to nearly iridescent pink flower color.     -   2. Large corolla produced throughout flowering season.     -   3. Exceptionally strong plant.     -   4. Above average quantity and quality of flower stems produced         during the flowering season.

PARENT COMPARISON

Plants of the new cultivar ‘ABLEIGONG’ are similar to plants of the seed parent, in most horticultural characteristics, however, plants of the new cultivar ‘ABLEIGONG’ differ in the following;

-   -   1. Flower color.     -   2. Flower size.

Plants of the new cultivar ‘ABLEIGONG’ are similar to plants of the pollen parent, in most horticultural characteristics, however, plants of the new cultivar ‘ABLEIGONG’ differ in the following;

-   -   1. Flower color.     -   2. Flower size.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘ABLEIGONG’ are comparable to the unpatented commercial variety Ranunculus ‘ABIOSHEKA’. The two Ranunculus varieties are similar in most horticultural characteristics; however, the new variety ‘ABLEIGONG’ differs in the following:

-   -   1. Vegetative carriage.     -   2. Floral size, the new variety has a smaller flower.     -   3. Floral color, the new variety has a lighter colored flower         which is more pink than purple.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color flowering plants of the new variety at approximately five months old, grown in a greenhouse.

FIG. 2 illustrates a close up of plant parts. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 6^(th) edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘ABLEIGONG’ plants grown in a greenhouse Camporosso Mare, Italy. The plant described has been cultivated under glass, planted in the months of September and described in the month of February. One must always refer to these conditions of season and culture, when considering the present description. By reason of different climate or culture conditions, differences may arise between certain characteristics of the plant and the corresponding characteristics of the description. It should be considered as normal and do not modify the essence of the present invention because it will possible to identify the plant by means of the totality of the characteristics given in the description. The rhizome has been planted on raised benches in a peat and pumice substrate mixture. The growing temperature ranged from 12° C. to 25° C. during the day and from 2° C. to 8° C. during the night. General light conditions are bright, normal sunlight. Measurements and numerical values represent averages of typical plant types.
